Abstract (en)

[origin: EP1924085A2] According to an aspect of the invention, there is provided a solid-state image sensing device characterized by including a pixel section (1) in which cells (11) are two-dimensionally arrayed in rows and columns on a semiconductor substrate, each cell including a photoelectric conversion unit, a reading circuit which reads out, to a detection unit, signal charges obtained by photoelectrically converting incident light by the photoelectric conversion unit, an amplifying circuit which amplifies and outputs a voltage corresponding to the signal charges stored in the detection unit, and a reset circuit which resets the signal charges of the detection unit, an exposure time control circuit (13, 14) which controls an exposure time during which the photoelectric conversion unit performs photoelectric conversion, and controls the exposure time to be equal for all cells, an A/D conversion circuit (3) which A/D-converts a signal output from the pixel section by changing a resolution of a signal level, line memories (5, 6) which store a signal converted by the A/D conversion circuit, and a signal processing circuit (20) which processes output signals from the line memories to have a linear gradient with respect to an optical input signal amount by controlling an amplification factor in accordance with a resolution of a pixel output signal after the A/D conversion circuit.
